Product Description

Cisco 7100 series VPN routers support Virtual Private Networks (VPNs) and provide an integrated
solution for security, quality of service (QoS), and service-level validation with emphasis on network
technologies such as encryption and tunneling using IP Security (IPSec), Layer 2 Tunneling Protocol
(L2TP), Generic Routing Encapsulation (GRE), and Layer 2 Forwarding (L2F) tunneling to ensure
private transactions over public data networks. Cisco 7100 series VPN routers are designed for the
enterprise WAN edge market and customer premises equipment (CPE) for the service provider as shown
in

  • Page 27: Flash Disks

    Cisco 7100 series VPN routers support up to two installed Flash Disks that contain the default Cisco IOS software image. Flash Disks can be installed in slot 0 and slot 1 of the PC Card slots located at the back of the router. Slot 0 is the top slot and slot 1 is the bottom slot.

  • Page 28: Sdram Memory

    To avoid potential problems when you install spare Flash Disks in the router, we recommend that you Note reformat all Flash Disks on a Cisco 7100 series VPN router that is running the Cisco IOS release recommended for your router during your regularly scheduled service times. The Flash Disk requires the designation disk0 or disk1 to format it.

  • Page 30: Slot

    Cisco 7100 series router slots are numbered 0 through 5. Interfaces in the Cisco IOS software are identified by a type, slot number, and port number. The number of physical ports depends on the type of modular port adapter or fixed interface.

In the following example, most of the status information for each interface is omitted:...

  • Page 32: Mac Addresses

    Each address is reserved for a specific port and slot in the router regardless of whether a port adapter resides in that slot. The MAC addresses are assigned to slot 3 in Cisco 7120 series routers and slot 4 in Cisco 7140 series routers. This address scheme allows you to remove a port adapter and insert the port adapter into other routers without causing the MAC addresses to move around the network or be assigned to multiple devices.

  • Page 33: Online Insertion And Removal

    The system recognizes the signals and the sequence in which it receives them. When you remove or insert a port adapter in a Cisco 7100 series VPN router, the port adapter pins send signals to notify the system, which then performs as follows: Rapidly scans the system for configuration changes.
